Good afternoon everyone,
Looking at a lot of YouTube videos about the Stage Fright, I can say there is a high chance I will want the Rate/Speed LED to be a little bit less bright. In general, I never leave the stock 4.7k resistor for the indicator LEDs, as that's a bit too bright for my eyes, and almost always increase the resistor value substantially.
Stage Fright schematic shows two resistors around it D2 - R51 (4.7k) before it and R52 (another 4.7k) in parallel.
I would appreciate if someone with a bit more experience could answer a couple of questions I have:
1. What is the purpose of the resistor in parallel to D2, which is R52, 4.7k?
2. Which of the resistors should I change to make the maximum brightness a bit lower?
3. Can messing around with R51 and R52 affect how the pedal sounds/works? I suspect not, but better safe than sorry.
Thanks in advance!
1 - The second resistor in parallel makes the LED go fully dark when it pulses (without it the LED only dims somewhat).
2 - You change both resistors. If you want less brightness, make both 10k.
3 - Only if the resistors are not high enough in value. At 4k7 or 10k, it's not an issue.
